Emerson PACSystems ™ Ethernet Switch SLM082

Emerson PACSystems ™  Ethernet Switch SLM082 

Product Core Overview 

（1） Product positioning

SLM082 is a powerful management industrial switch suitable for harsh industrial environments such as wide temperature, high dust, and humidity. It supports web, console (CLI), third-party SNMP software, and exclusive "PACSystems Ethernet Switch Configuration Tool" for management, and can configure multiple switches simultaneously and monitor their status.

（2） Software core functions

Specific description of functional categories

Network redundancy supports the world's fastest redundant Ethernet ring (with a recovery time of less than 10ms when 250 devices are cascaded), enabling ring coupling and dual home topology; Compatible with RSTP (802.1w) Fast Spanning Tree Protocol

Network management supports the SNMP v1/v2/v3 protocol; Support VLAN partitioning based on port/802.1Q standards; Support LLDP (Link Layer Discovery Protocol) to automatically discover network node information

Event notifications can generate event alerts through email (SMTP), SNMP Trap, and relay output

Traffic control supports 802.1p Quality of Service (QoS) to ensure real-time traffic; Support IGMP Snooping multicast filtering to reduce network bandwidth usage

Security protection supports port enable/disable, MAC address based port security, 802.1x port authentication, and Radius centralized password management; SNPv3 encryption authentication

（3） Hardware core features

Power supply: Three redundant DC inputs.

Environmental adaptability: working temperature -40~70 ℃, storage temperature -40~85 ℃, working humidity 5%~95% (no condensation), protection level IP30.

Port configuration: 8 10/100Base-T (X) Ethernet ports (RJ45 interface), 2 100/1000Base-X SFP optical ports, and 1 Console port.

Physical dimensions: 52mm (width) x 106mm (depth) x 144mm (height).

Hardware Installation

SLM082 supports two installation methods to meet the needs of different industrial scenarios:

（1） DIN rail installation

The switch backplane comes with a DIN rail kit, which can be directly fastened to the standard DIN rail for fixation. The installation steps are simple and do not require additional drilling.

（2） Wall mounted installation

The packaging contains a wall mounted panel, which needs to be punched on the wall according to the dimensions indicated in the manual (such as aperture, hole spacing, etc.). After fixing the wall mounted panel with screws, the switch can be installed.

Hardware interface and indicator lights

（1） Front panel interface (Table 3.1)

Interface Type Quantity Function Description

10/100Base-T (X) ports with 8 RJ45 interfaces, supporting automatic negotiation (rate/duplex mode), default rate "automatic", duplex "automatic", flow control "disabled"

100/1000Base-X SFP ports with 2 optical ports, used to connect fiber optic modules and support high-speed data transmission

Console port with one RJ45 interface, connected to the computer via an RS-232 adapter cable for CLI management

Press the Reset button for 5 seconds to restore the switch to factory settings

（2） Meaning of front panel indicator lights (Table 3.2)

LED identification color status description

The green constant light of PW1/PW2/PW3 corresponds to the activated power supply module (PW1/PW2) or power interface (PW3)

R. The M (Ring Master) green constant light switch is the master node (Ring Master) of the redundant ring

The redundant ring with green constant brightness has been enabled;

Slow flashing: Redundant ring topology abnormality;

Flash: Redundant ring is working normally

Fault: The yellow light is constantly on, indicating a power failure or port interruption/malfunction

10/100Base-T (X) port LNK/ACT green constant light: port link established;

Flashing: The port is transmitting data and the link and activity status of the corresponding Ethernet port

10/100Base-T (X) port Full Duplex yellow constant light port works in full duplex mode

SFP port LNK/ACT green/yellow constant light: optical port link established;

Blinking: The optical port is transmitting data, and the corresponding link and activity status of the optical port are flashing

（3） Top panel component

Terminal block: includes PW1/PW2 (12-48V DC power input) and relay output interfaces（ 1A@24VDC ）.

Power interface (PW3): 12-45V DC power input socket.

Reset button: Press for 3 seconds to reset the device, press for 5 seconds to restore factory settings.

Console port: RJ45 interface, used for CLI management connection.

Cable Configuration

（1） Ethernet cable

Applicable standards: 10BASE-T supports Category 3/4/5 unshielded twisted pair (UTP), while 100BASE-TX requires Category 5 UTP.

Maximum transmission distance: Both are 100m (328 feet), with RJ45 connectors.

Pin definition: In 100BASE-TX/10BASE-T cables, pins 1/2 are used for sending data and pins 3/6 are used for receiving data; Supports automatic MDI/MDI-X functionality, allowing for direct connection between computers and switches (without the need for crossovers).

（2） SFP optical module and fiber optic

Optical module type: Supports multi-mode (transmission distance 0-550m, wavelength 850nm, fiber specifications 50/125 μ m or 62.5/125 μ m) and single-mode SFP modules, with LC connectors.
